As I've been told it was named SVR5 to mark inclusion of enterprise-level
features (and yes, for marketing reasons):
- better CPU scalability with modular support for different platforms
(initially UW7 was up to 8 CPUs well and 12 CPUs so-so, now up to
16 CPUs well)
- support for over 4GB of memory
- support for large areas of shared memory attached to great many processes
- multi-path I/O support (a disk can be connected to 2 or more SCSI buses)
- integrated volume manager (from Veritas, terrible thing, and often broken)
- hot-swappable disks
- hot-pluggable PCI cards
- high availablilty clustering (Reliant from Veritas, terrible thing, and
sometimes broken)
Internally it had significant extensions in the multiprocessor
support, memory and re-designed I/O subsystem.
